The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of heat-exchanger fin.
With reference to Fig. 1, Fig. 2 and Fig. 7, Fig. 1 is the structural representation of fin one embodiment in unit in the utility model heat-exchanger fin; Fig. 2 is along the cross-sectional view of A-A direction in Fig. 1; Fig. 7 is the structural representation of the utility model heat exchanger.
In the utility model embodiment, this heat-exchanger fin is located between the left and right header of heat exchanger, and is connected with the flat tube 30 of this heat exchanger.This heat-exchanger fin comprises some interconnective unit fin 10, is provided with flat tube groove 11 between every two unit fin 10, and this flat tube groove 11 is used for being connected with flat tube 30.Each unit fin 10 comprises the symmetrically arranged some shutters 12 in up and down, and this shutter 12 leeward side rear ends are provided with rhone 13, and this rhone 13 is used for getting rid of condensed water or defrosting water.Be provided with cross reinforcing 14 between shutter 12, this cross reinforcing 14 is for increasing the heat-exchanger fin transverse strength.Arranging of cross reinforcing 14 can increase unit fin 10 transverse strengths, avoids because of the heat-exchanger fin insufficient strength, and assembling or welding process generation heat-exchanger fin laterally collapse.In figure, the arrow B direction is the air intake direction.
Under heating condition, the microchannel flow evaporation of cold-producing medium in flat tube 30 that temperature is lower makes flat tube 30 outside wall surface and unit fin 10 surface temperatures be lowered.When humid air stream during through heat exchanger, carry out heat exchange with flat tube 30 outer surfaces and unit fin 10 surfaces, and separate out from the teeth outwards condensed water, emit sensible heat and latent heat and by cooling and dehumidification.Open shutter 12 on heat-exchanger fin and can effectively upset the humid air stream temperature boundary layer, add the mixing of air blast, can strengthen the heat exchange efficiency of heat-exchanger fin, shutter 12 leeward sides are used for condensed water or the downward rhone 13 of discharging of defrosting water, under the Wind power propelling effect, condensed water or defrosting water are constantly assembled to this rhone 13 in the horizontal, and condensed water or defrosting water constantly prolong this rhone 13 and drains downwards under Action of Gravity Field.
In the lower situation of environment temperature, because the cold-producing medium evaporating temperature in flat tube 30 is lower, when temperature lower than through the humid air freezing point of heat-exchanger surface the time, flat tube 30 surfaces on heat exchanger and heat-exchanger fin reach frosting condition and certain frost that can condense, when system enters when defrosting, cold-producing medium heat release and condensation in heat exchanger; Liberated heat melts the frost of fin surface, the discharge principle of the discharge of defrosting water and condensed water identical (first starting blower fan before heating changing over to).Because defrosting water can be drained smoothly, effectively suppress next frosting cycle frost layer and thicken, also solved the problem of freezing simultaneously.Reduce the windage principle when freezing with heating operation identical, can upset temperature boundary layer equally, add the mixing of air blast, strengthen heat transfer effect.
The heat-exchanger fin that the utility model proposes can make condensed water or the defrosting water on heat exchanger in time drain, change existing condenser condenses water or defrosting water and get rid of not smooth situation, slow down frosting speed, can also strengthen the heat-exchanger fin radiating efficiency simultaneously.
In the above-described embodiments, also be provided with some walings around shutter 12, this waling is for increasing the heat-exchanger fin longitudinal strength.Wherein this waling comprises the first waling 15 of the front end of being located at shutter 12 inlet sides and is located at the second waling 16 of the rear end of shutter 12 inlet sides.The first waling 15 and the second waling 16 that shutter 12 front and back arrange can increase unit fin 10 longitudinal strengths, avoid because fin strength is inadequate, and assembling process generation fin vertically collapses.By making the change of heat-exchanger fin sheet type, strengthen the intensity of heat-exchanger fin, to avoid in assembling process because fin is thin, welding temperature is high to be caused fin to deform and affects heat transfer effect and heat exchanger bulk strength.
In the above-described embodiments, shutter 12 rear and front ends respectively are provided with a through hole 17, this through hole 17 edges are provided with the upwards pitch of fins stator 18 of turnover, wherein this through hole 17 is used for passing heat-exchanger fin to be fixed on left and right header and flat tube 30 for support bar 20, makes the heat exchanger overall structure more firm.Pitch of fins stator 18 is used for fixing every two heat-exchanger spacing of fin, makes the heat exchange of heat exchanger more evenly, efficiently.
In the above-described embodiments, also be provided with heat transfer groove 19 near the second waling 16, this heat transfer groove 19 is used for strengthening the heat-exchanger fin heat transfer effect, further improves the heat exchange efficiency of heat exchanger.
With reference to Fig. 3, Fig. 4 and Fig. 7, Fig. 3 is the structural representation of fin another embodiment in unit in the utility model heat-exchanger fin; Fig. 4 is along the cross-sectional view of C-C direction in Fig. 3; Fig. 7 is the structural representation of the utility model heat exchanger.
The present embodiment is from the different of above-described embodiment, in the present embodiment, 15 one-tenth split settings of the first waling of the front end of shutter 12 inlet sides of unit fin 10, be divided into two sub-reinforcements, the reinforcement that wherein vertically arranges has guaranteed the longitudinal strength of shutter 12 front ends of unit fin 10, avoids heat-exchanger fin to occur vertically to collapse in assembling process, and due to its convex, effectively upset inlet side air stream, the 10 front end heat exchange of enhancement unit fin; The reinforcement of horizontally set has guaranteed the transverse strength of shutter 12 front ends of heat-exchanger fin, avoid heat-exchanger fin to occur laterally to collapse when the assembling flat tube, intensity that also can corresponding enhancing heat-exchanger fin under the welding high-temperature condition, when avoiding high temperature, fin deforms and makes between different heat-exchanger fins and bond together.In addition in the present embodiment, pitch of fins stator 18 directions of shutter 12 front ends of unit fin 10 are vertical direction, more convenient its draining.
With reference to Fig. 5, Fig. 6 and Fig. 7, Fig. 5 is the structural representation of fin another embodiment in unit in the utility model heat-exchanger fin; Fig. 6 is along the cross-sectional view of D-D direction in Fig. 5; Fig. 7 is the structural representation of the utility model heat exchanger.
The present embodiment is from the different of above-described embodiment, in the present embodiment, the shape of the pitch of fins stator 18 of unit fin 10 and varying in size, the present embodiment adopts is that each pitch of fins stator folds one section aluminium for the fixing spacing of two heat-exchanger fin in both sides 18 Shang Xia.When unit fin 10 greatly to a certain extent, namely when flat tube 30 spacings during greater than 13mm, adopt the present embodiment mode stator apart from because the both sides, up and down are simultaneously stressed, between adjacent heat-exchanger fin, the assembly welding process is not easy distortion and bonds together.
